Abstract

This study carried out the measurement and analysis of indoor air quality at the passenger terminal of Jeju Airport from 2014 to 2018 to 2018. Measured contaminants for indoor air quality degradation were targeted at PM-10, PM-2.5, carbon dioxide (CO2), formaldehyde (HCHO), carbon monoxide (CO), nitrogen dioxide (NO2), radon (Rn), and volatile organic compounds (VOCs), as provided under the Act on Management of indoor air quality. The measurement method was carried out in accordance with the National Institute of Environmental Research Notice "Internal Air Quality Process Test Standards," and the number of measurements was measured in accordance with the "Airport Environment Control Standards" specified in the Land, Infrastructure and Transport Ministry. The effects of indoor and outdoor environments were investigated and compared and analyzed to identify the factors affecting the measurement results. Finally, the measurement results were compared with the criteria specified in the Maintenance Standards and Recommendation Standards of the Indoor Air Quality Management Act to determine whether they were appropriate. According to the measurement and analysis of indoor air quality, PM-10 was measured at 25 - 66.9 μg/m3, PM-2.5 was 8.9 - 25.2 μg/m3, CO2 was 497.5 - 735.3 ppm, Formaldehyde (HCHO) was 9 - 49.1 μg/m3, and carbon monoxide (CO) was measured at 0.1 - ppm, Nitrogen dioxide (NO2) was 0.007 - 0.037 ppm, radon (Rn), 6.48 - 47.18 μg/m3, and total volatile organic compounds (VOCs) were measured at 57.5 - 202 μg/m3. As an investigation into the effects of indoor air quality on indoor air quality by indoor environment, it was confirmed that there could be an inflow of outdoor air through indoor and outdoor ventilation, the generation of metabolites due to the activities of the occupants, building materials such as internal paints, and everyday items such as clothing worn by passengers. Comparing the indoor concentration effects of PM-10, PM-2.5, CO and NO2 due to the inflow of outdoor air, the effects of indoor concentration due to the increase and decrease of outdoor air quality were not confirmed. Based on the measurement results of indoor air quality at Jeju Airport's passenger terminal, it was confirmed that the results were within the standard in all items.
